Be it known that 'I, RoBnRT E. OARSWELL, a citizen of the UnitedJStates,residing at Minneapolis, in the'county of Hennepin. and

State of Minnesota, have invented certain new and useful Improvements 1nCombined Ventilators and Advertising Devices; and "I do hereby declarethe following to be a full, clear, and exact description'of the in-.vent1on,such as Wlll enable others skilled in the art to which itappertains to make and use the same.

My present invention has for its object to' provide a combinedadvertising device and window ventilatorv of simple construction andattractive appearance; and to such,

ends, generally stated, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claims.Y

In the preferred embodiment of the invention, the body outlines of anautomobile are printed, stamped or otherwise marked on the face of arectangular board which is adapted to be inserted in a partly openedwindow. The wheels of this dummy automobile are revoluble and the spokezones thereof are formed with oblique propeller blades which cause thewheels to rotate when subjected to even a light draft. The board onwhich the automobile is marked or to which the representation thereof isapplied, is provided in line with the wheels panying drawings whereinlike characters indicate like parts throughout the several views.

Referring to the drawings, Figure l is an elevation looking at the faceof the board and the dummy automobile which is applied thereto; Fig. 2is a detail in section on the line m 00 on Fig. 1; and Fig. 3 is adetail in elevation showing one of the closures or gates for cooperationwith the air passages in the ventilating board.

The so-called ventilating board is indicated by the numeral 1 and may bemade of cardboard, wood, metal or any other suit-- able material, andshould be of such size Specification of Letters' Patent.

that it will fit under the sashof an open or partly opened window.

The numeral 2 indicates the dummyauto- 'mobile which, as indicatedmnaybe printed,

formed in the wheels. The numeral 4 board 1 in line with the indicatesthe wheel spindles which, as shown, are rigidly-secured.

to -supportingbars 5 formed asapart of the board 1, and extendeddiametrically across the air passages 3. On the spindles a, the wheels 6are preferably stamped from thin sheet metal and provided with hubportions 7 and with spokes represented by portions of oblique propellerblades 8.

The numeral 9 indicates the closures or gates which are adapted to closethe air passages 3 of the board 1, and which, as shown, are providedwith radial notches 10 adapting them to straddle the spindles a, justbetween the board 1 and the hubs of the .wheels 6. WVhe'n these gates 9are applied, as shown at the left in Fig. 1, they will close thepassages 3 so that there will be no passage of airthrough the same, andhence, the wheel or wheels will not rotate. When the gates 9 areremoved, there will, as already indicated, be a draft through thepassages 3 which, acting against the, propeller blades 8 of the wheels,will cause the latter to rotate. This device, therefore, serves as anefficient ventilator and at the same time, because of its veryattractive and novel appearance, given by the rot-w tion of the wheels,it is especially well adapted for an advertising device. Moreparticularly, it is adapted for an advertising device for various makesof automobiles, but it may be used as an advertising device for variousother wheeled vehicles. 7
